Finite element analysis of textile composite preform stamping

摘要

The forming or draping of a textile composite preform may result in large changes in the fibrous microstructure of the preform. This change in the local fiber orientation leads to significant changes in the fabric permeability as well as the mechanical properties Of the ensuing composite structure. Therefore, this change in orientation of the tows of the preform needs to be known accurately to Calculate the various effective properties of the composite.
